Carlsen retains Chess crown

Norwegian Magnus Carlsen extended his dominance over the chess world on Wednesday by winning the World Chess Championship for the third consecutive time on Wednesday, beating his Russian challenger Sergei Karyakin in a tiebreaker.The win puts Carlsen closer to the status of chess legends such as Garry Kasparov, who dominated the game for 15 years.Although Karyakin foiled predictions by tying Carlsen in 12 regular rounds, the Norwegian champion beat him in the final phase of four quick-fire extra games.The battle for the world chess crown ended up in the dramatic tiebreaker on Wednesday after a win apiece and nine draws.So the young stars -- both aged just 26 -- headed into the chess equivalent of extra time in soccer. Unlike the earlier rounds, which lasted an average of six hours, the rapid-play rules meant the players had just 25 minutes each, so each game was over in an hour.The accelerated games left plenty of opportunity for harried mistakes, and while predictions were difficult, Carlsen -- a king of the blitz format and world number-one since 2010 -- had remained favorite.
